Fabricated bridge guardrail
The invention relates to an assembly type bridge guardrail. The bridge guardrail comprises a prefabricated bridge deck slab and a prefabricated guardrail body. The prefabricated guardrail is provided with a reserved channel penetrating through the bottom face of the prefabricated guardrail, and the prefabricated bridge deck slab is provided with an adjustable embedded part in an upward protruding mode corresponding to the reserved channel. The adjustable embedded part comprises a steel plate, a bolt sliding box and a bolt, the bolt sliding box is connected to the bottom surface of the steel plate, the steel plate is provided with an oval long hole communicated with an inner cavity of the bolt sliding box, and the length direction of the oval long hole is parallel to the distribution direction of the adjustable embedded part; the bolt is vertically arranged and comprises a bolt head and a screw, the bolt head is located in the bolt sliding box, and the screw penetrates through the oval long hole and penetrates into the reserved channel. In the bridge guardrail, the bolts can slide in the bolt sliding boxes along the oval long holes, so that the positions, inserted into the reserved channels, of the embedded parts are adjustable, the position deviation of the embedded parts and the reserved channels can be corrected, and the success rate of connection of the prefabricated guardrail and the prefabricated bridge floor is increased.
本发明涉及一种装配式桥梁护栏，该桥梁护栏包括预制桥面板以及预制护栏；预制护栏设有贯通其底面的预留通道，对应预留通道，预制桥面板向上突出设有可调预埋件；可调预埋件包括钢板、螺栓滑动盒、螺栓，螺栓滑动盒连接于钢板的底面，钢板设置有与螺栓滑动盒内腔连通的椭圆形长孔，椭圆形长孔的长度方向平行于可调预埋件的分布方向；螺栓竖直设置，其包括螺栓头部与螺杆，螺栓头部位于螺栓滑动盒内部，螺杆穿过椭圆形长孔穿入预留通道内。该桥梁护栏中，螺栓可沿椭圆形长孔在螺栓滑动盒内滑动，使得预埋件插接入预留通道部分的位置可调节，进而能够纠正预埋件与预留通道的位置偏差，提高预制护栏与预制桥面连接的成功率。
